Aiming at the problems of high remodel difficulty and cable laying cost in heat intelligen- tial measuring and management, the sensor network technology was applied in heat data collection and transmission. After the research of node structure and working principle in wireless heat measuring network, a heat measuring system based on ISM sensor network was established, moreover, a wireless trans- fer method according to S - MAC protocol was presented. The nodes＇ performance tested by RSSI param- eter showed that the ISM sensor network can greatly reduce data collection cost, increase the flexibility and extensibility of the system upon the wireless heat data collection requirement. The protocol can en- sure the effectiveness of data transmission and can realize the heat remote measuring and management through the integration of GSM network.
